Playing in Vegas

[ramjam]

I am a beginning online player. I started a couple of months ago after having only played poker two or three times for pennies during my youth. I have studied a number of standard texts (including TOP and HEPFAP). My record at online HE ring games (mostly 1-2, some .25/.50) since I started compiling data on January 1 is +$203 over 38 hours (I would estimate that I blew about $50 bucks when I started in December).

I will be travelling through California and Nevada and will stopover in Vegas for three days.

Perhaps someone could advise me:
-What are the lowest limit HE games available in casinos (and in which ones)?
-Would it be advisable for me to play in those games given my limited experience - or am I likely to be a big dog?
